14.1.6 Limits and Power Adjustment
The voltage limits can be set using the ”234.01 GnVtgMin” and ”234.02 GnVtgMax” parameters
and the frequency limits for generator operation can be set using the ”234.05 GnFrqMin” and
”234.06 GnFrqMax” parameters. If the values are outside these permitted limits, the generator is
disconnected. Slightly narrower limits apply to generator connection.

Power-Dependent Generator Start
Warm-up times, minimum run times and shut-off delay times are also maintained for power
dependent generator starts.
System Voltage (AC)
The system voltage (AC) depends on the generator voltage when the generator is running.
